The door runs from a phone, and safety beams never came up
Why it happens
App control usually gets added for convenience. Nothing's wrong with the door, so nobody thinks to ask what else the setup needs.
Why it matters
A door you run from your phone can close while you can't see it. That's the exact case one opener maker's manual singles out when it says safety beams must be fitted. The same manual says to put the wall button somewhere you can see the door.
Response
Tell Thom how the door is run when you book. On a service he tests the opener and its safety reversal. If the opener is being replaced, he tests the new one before he leaves.
